A compact, modular sonar assembly for use on the bow of a ship having separate transmitting and receive arrays confined within a single acoustic housing. The narrow and compact design fits much better into the hydrodynamically desirable bulbous bow deign than the typical bow dome sonar design and achieves good performance at a low cost with reduced size and weight.

1. A sonar assembly comprising:a) an elongated array of sequentially juxtaposed transmitting transducer elements stacked within and confined by a pressure housing, each transducer being independently connected to drive circuitry; b) opposite ends of the pressure housing being attached internally to first and second portions of a frame, which frame is mountable on a ship; c) a plurality of staves sequentially positioned around a periphery of the frame, each stave extending between the first and second portions of the frame; d) a series of acoustic receive hydrophones positioned along each stave, each hydrophone being independently connected to signal detecting circuitry; and e) an acoustically transparent housing encapsulating the frame.
